After installing a few extensions, they for some reason don't show up in the Connect Manager. Modules like: M2E, Jemoon_Htmlminify, Lest_FPC, PulseStorm_Launcher, etc.

They are all installed, but they are not listed there. And when I try and upgrade them (by installing them again via Connect Manager), I get this error:

CONNECT ERROR: Package 'm2epro_ebay_magento' is invalid './app/code/community/Ess/M2ePro/Block/Adminhtml/Account/Grid.php' already exists

It then halts my magento installation, until I delete the file maintenance.flag in my magento folder.

I've tried running:

  1. ./mage sync but it's not working.

What's going on here? I'm running Magento 1.9

  • Did you install all these extensions via the Magento Connect Manager?

  • Yes, all the extensions were installed via Connect Manager

  • Normally, each installed extension has an XML file under var/package/. Maybe the files of these extensions are missing there because of e.g. a permission issue? Additionally, consider not using the Connect Manager - it creates more problems than it solves.

  • Seemingly you are right! The troubled extensions are set at permission level 666, while the others are 777. I tried to change said extensions to 777 but it still didn't help!?? Any ideas?

  • As long as the XML files are present under var/package/, the Connect manager should show them anyway...

I had this problem also. Running a chown. Did not work for me.

What I had to do was, rename Cache.cfg and connect.cfg. Looks they had corrupted.Once I renamed next time I accessed Connect. Voila, new versions of the files were created. And I could see all my extensions again.


Cache.cfg and connect.cfg had nobody:nobody as the username:group in the downloader/ folder.

Logging into root account, and running chown username:group <file> on those two files to the proper username:group solved this problem.


Download the extension again and from the root copy package.xml into /var/package open the package.xml file.

Get the name then rename file file to match I,e in my case I had to rename package.xml to M2epro_ebay_magento-6.4.10.xml.

Then I logged out of Magento connect manager and logged back in. Now my extension shows.
